[patch 06/10] Add return value to reserve_bootmem_node()

[Greg KH]

2.6.25.9-stable review patch.  If anyone has any objections, please let
us know.

------------------ 
From: Bernhard Walle <bwalle@xxxxxxx>

commit 71c2742f5e6348d76ee62085cf0a13e5eff0f00e upstream

This patch changes the function reserve_bootmem_node() from void to int,
returning -ENOMEM if the allocation fails.

This fixes a build problem on x86 with CONFIG_KEXEC=y and
CONFIG_NEED_MULTIPLE_NODES=y
